Answer:
The correct answer would be - overpopulation that leads to fewer resources for the population that leads to an increase in death rate.
Step-by-step explanation:
The carrying capacity of a population is the capacity of an ecosystem to bear up to a definite quantity of a population where the resource and services are present to help in the growing population.
In other words, it is the number of individuals that can be sustained by an ecosystem. If a population exceeds carrying capacity it means there is not plenty of resources available that lead to the competition and ultimately increase in the death rate.
Thus, the correct answer is - increase in the death rate.
